A defibrillator works by delivering an electric shock to the heart to restore its normal rhythm. When the heart is in a life-threatening rhythm such as ventricular fibrillation or ventricular tachycardia, the defibrillator sends an electrical current through the heart muscle to depolarize the cells and allow the heart to reestablish an organized rhythm. This shock can help stop the abnormal rhythm and allow the heart to resume pumping blood effectively. Defibrillators are crucial in treating sudden cardiac arrest and can save lives by quickly restoring a normal heart rhythm. **
